She thinks his health issues "aren't all settled" and that's it's "iffy" he'll be CEO in two years. In fact, it seems like she's feeling his return would largely be to handle the transition to a mystery successor (besides work on that damn tablet): "There's some transition, but that won't be announced for a while. I feel that there's another person that won't surface right away." Is it Phil? Tim? Jony?
